Im hoping someone here can help me out. I had installed a Kenwood DNX893S expensive stereo on a 2013 yukon denali. The features are great and better than the stock. I also have the maestro so i retained mostly everything (lost ability to have 2 channels on the wireless headphones). The problem i am having is with the wireless headphones. I have noticed that it works off and on. When its not working i have to turn the car off and than back on a few times to get it to work. I had it at the GMZ dealership a few times. The first time they said it was the IR transmitter-i replaced it and i did he same thing. The second time, they told me it was the control module, they replaced it and it still did the same thing. I also took it to the car stereo place that did the install and they checked the kenwood out and said the problem is somewhere in the wiring because everything was working up to the factory harness. Im looking for help as i just want my kinds to be able to listen to their movie and my wife and i dont have to hear it. any ideas what the problem is?
